What and how many elements it's composed of
A chemical formula tells you the number of each type of atom in the molecule or structure.
It tells what elements are present in a molecule and how many atoms of each element are present.
A molecule contain two or more atoms of chemical elements; each molecule has a specific formula.
Formula: C12H22O11
That each molecule contains 1 atom of carbon and 4 atoms of hydrogen.
The central atom in the molecule with the chemical formula ClO2 has a hybridization of sp2.
A chemical formula is the representation of a molecule of a chemical compound; all the atoms from the molecule of this compound need to be represented in the formula.
The chemical formula of sucrose is C12H22O11.
The chemical formula CO2 tells you that the molecule consists of one carbon atom (C) bonded to two oxygen atoms (O). This compound is known as carbon dioxide and is a colorless gas at room temperature.
H if you're talking about its natural form, it would be H2
A chemical formula provides information about the types and numbers of atoms present in a molecule. It tells you the elements that make up the molecule and their ratios.
